Packet Format
These parameters provide instruction for how packet dissection is performed in AppResponse 11, modifying the way in which information is collected from the packets, without altering the packets themselves. For example, these parameters can be used to determine whether the inner or the outer TCP/IP headers will be used with GRE encapsulation.
Supported Parameters
◼ L3 GRE — The Analyze inner IP only option is selected by default, causing packet analysis to be perfomed on the inner packet. Selecting Analyze outer IP only disables this feature, causing packet analysis to happen only on the outer packet.
◼ VxLAN — The Analyze VxLAN header option is selected by default, causing the outer packet to be analyzed. If the Ignore VxLAN option is selected, instead, then only the inner packet will be analyzed. That means that VxLAN views will show no data, since the inner packet likely does not use VxLAN.
◼ MAC in MAC — The Recognize 802.1ah option is selected by default, causing the 802.1ah frame to be recognized, and the rest of the frame will be parsed. If, for example, an IP header follows, the packet will be identified correctly as an IP frame. If the Ignore (entire) 802.1ah packets option is selected, packet dissection will stop at the 802.1ah header; the IP packet of the previous example will not be recognized as IP.
◼ UDP Port for VxLAN — This is set to 4789, by default.
◼ MPLS Level — By default, the bottom MPLS Label (1) is set. This is the position from the bottom of the MPLS label stack, to be used. Values range from 1 to 10; values start from 1 (bottom of the stack) and increase.
◼ VLAN Level — By default, VLAN Level 1 is set. Values range from 1 - 255; values start from 1 and increase.
